Principle of Operation
WARNING:
When you are going downhill, your vehicle speed may increase above the set speed. The system will not apply the brakes but a warning displays. Failure to follow this warning could result in serious personal injury or death. |
The system allows you to set a speed, to which your vehicle then becomes limited. The set speed becomes the effective maximum speed of your vehicle, but with the option to temporarily exceed this limit if required.
Using the Speed Limiter
Note:
The set speed limit can be intentionally exceeded for a short period of time if required, for example when overtaking.
The system is operated by adjustment controls mounted on the steering wheel.

Switching the System On and Off
Press LIM to set the limiter in standby mode. The information display prompts you to set a speed. Press LIM again to switch the system off.
Setting the Speed Limiter
- Press SET+ or SET- with the limiter in standby mode to set the limiter to the current vehicle speed. The LIM symbol in the information display shows as green.
- Press SET+ or SET- to select your desired speed limit. The speed is displayed in the information display and stored as the set speed.
- You can adjust the set speed in small or large increments. Press the button once to adjust the set speed in small increments. Press and hold the button to adjust the set speed in large increments.
- Press CNCL to cancel the limiter and place it in standby mode. The LIM symbol in the information display shows as grey.
- Press RES to resume the limiter. The LIM symbol shows as green.
Intentionally Exceeding the Set Speed Limit
Firmly depress the accelerator pedal to temporarily switch the system off. The system reactivates once your vehicle speed drops below the set speed.
System Warnings
If you accidently exceed the set speed, the set speed indicator in the information display flashes and an audible warning tone sounds.
If you intentionally exceed the set speed, only the set speed indicator in the information display flashes.
Using the Intelligent Speed Limiter (If Equipped)
WARNING:
You are responsible for controlling your vehicle at all times. The system is designed to be an aid and does not relieve you of your responsibility to drive with due care and attention. Failure to follow this instruction could result in the loss of control of your vehicle, personal injury or death. |
Note:
When driving between countries that use different units of measure (miles per hour or kilometers per hour), there may be a delay before the system changes between speed limit units. During this time, the display screen for the speed limiter may differ from the actual posted speed limit. For best performance, make sure that the navigation SD card is in the navigation media port.
The system allows you to automatically limit your vehicle speed to the speed limit that is detected by the Traffic Sign Recognition system.
You can change the speed limiter mode between manual and intelligent in the information display. See
General Information.
You can select a permanent set speed tolerance that is in addition to the detected speed limit through the tolerance menu in the information display. See
General Information.
Switching the System On and Off
Press LIM to set the limiter in standby mode. The information display prompts you to set a speed or show the detected speed limit as the set speed. The Intelligent Speed Limiter does not limit the vehicle speed in standby mode. The Auto LIM symbol and set speed indication show as grey in standby mode. Press LIM with the limiter in standby mode to switch the system off.
Intentionally Exceeding the Set Speed Limit
Firmly depress the accelerator pedal to temporarily switch the system off. The system reactivates once your vehicle speed drops below the set speed.
Setting the Speed Limiter
- Press RES with the limiter in standby mode to set the limiter to the detected speed limit. Speed limitation activates and the Auto LIM symbol shows as green.
- Press SET- with the limiter in standby mode to set the limiter to the current vehicle speed. Speed limitation activates and the Auto LIM symbol shows as green.
- Press SET+ or SET- to gradually change the current set speed to your desired speed limit. The speed is displayed in the information display and stored as the set speed.
- You can adjust the set speed in small or large increments. Press the button once to adjust the set speed in small increments. Press and hold the button to adjust the set speed in large increments.
- Press CNCL to cancel the limiter and place it in standby mode. The Auto LIM symbol shows as grey.
- Press RES to resume the limiter. The Auto LIM symbol shows as green.
- The limit speed adapts to the speed limit detected by the Traffic Sign Recognition system. The Intelligent Speed Limiter does not react to speed limits shown with a supplementary sign by the Traffic Sign Recognition system. If there is no speed limit information available, the limiter switches to standby mode.
System Warnings
If the set speed is automatically set to a lower value than your current vehicle speed, the set speed indicator in the information display flashes and an audible warning tone sounds if you are continuously exceeding the set speed.
If you accidently exceed the set speed, the set speed indicator in the information display flashes and an audible warning tone sounds.
If you intentionally exceed the set speed, only the set speed indicator in the information display flashes.
If the Traffic Sign Recognition system detects a speed limit outside the operational speed range, an audible warning tone sounds and the system switches to standby mode.
